Shown below is the chemical structure of F, one of the 20 proteinogenic amino acids. This amino acid is also occasionally used as a buffer system in parenteral preparations. F OH NH2 HN (i) Redraw F and insert the valence non-bonding electron pairs on each appropriate atom of the structure. Amino acid F has three pKa values (pKaj = 1.82, pKa2 = 6.00, pka3 9.17). (ii) Draw the predominant structure of amino acid F as it would exist at (a) pH 4 and (b) pH 11. Explain your answers. 17.5 marks]
